No award ceremony. No press conference. No more tennis - “definitively.”

As the media frenzy around Emma Raducanu, the 18-year-old Briton whose US Open victory on Saturday (September 11) established her as the first qualifier to win a Grand Slam event, continues to bubble and seethe, there is already much speculation over how well this sunny and super-talented performer will cope with the pressure of expectation.

There were those who nodded sagely when Raducanu, after qualifying for this year’s Wimbledon Championships on a wildcard and reaching the fourth round, pulled out of her match in the second set due to breathing difficulties.

Numerous instant theories concerning psychological flaws duly fell to earth as she struck the ace that earned her the title in New York to conclude a 6-4, 6-3 win over Canada’s 19-year-old Leylah Fernandez that had seen her fall heavily and cut her leg at a crucial point in the second set.

Borg was also a Grand Slam champion at 18, having claimed the French Open title he would go on to win five more times just a couple of weeks after his birthday.

The 1981 French Open turned out to be the last of his 11 Grand Slam wins, with the others coming, in five successive years, at Wimbledon.

Two months before he walked away from the game Borg’s unerring record of success in SW19 had come to an end as McEnroe’s irrepressible spirit and talent earned him a 4-6, 6-2, 6-4, 6-3 win over the opponent whose strength, footwork, physical fitness, technical ability, discipline and almost alien mental durability had made him invincible on those London lawns since 1976.

In one of the two tennis arenas where he had reigned supreme this Wimbledon defeat, which followed his epic 1-6, 7-5, 6-3, 6-7, 8-6 victory over McEnroe to win the title the previous year - a final which many still believe is the greatest that event has witnessed - seemed to mark a tipping point at the top of the men’s game.

But, as Borg revealed to Tim Adams in a 2007 interview with The Observer, he had felt the tipping point occur in the Wimbledon final a year earlier, when he was one set away from what will always be regarded as his most epic victory.

Borg surrendered seven match points in the fourth set before McEnroe levelled the match at 2-2 by winning the tie-break 18-16. That was when he felt he could be beaten…

"Watching myself losing that last point, 18-16, I can feel that walk back to the chair now as if it was yesterday," he told Adams. "That was the toughest moment in my tennis career, that walk.

"I knew John thought he would win the match. I thought he would win the match. I don't know how I regrouped. If he had broken me in the first game of the fifth set I would have lost, but I won from love-30 and then I played just unbelievably well, hardly lost a point on serve and won the match. That was the strongest set, mentally, in my tennis career."

But the seed of doubt had sprouted at that moment.

When he lost his Wimbledon title the following year, there was another unwelcome revelation for him.

"I felt I was much the better player that day," he added. "But I just wasn't so focused. And when I lost what shocked me was I wasn't even upset. That was not me: losing a Wimbledon final and not upset. I hate to lose. It was the same at the US Open. Losing to John again I was relieved the match was over."

For Borg, it was over.

The following year he entered his "home" championship, the Monte Carlo Open, making the quarter-finals. In January 1983, aged 26, he announced he was retiring from the game.

Bizarrely, in 1991, something stirred deep in his soul and he turned up at the red clay courts of the Monte Carlo Country Club once again equipped with an old-style wooden racket and an inexplicable desire to take part in the annual championships despite having had no practice or significant training.

He lost his first match. Over the course of the next two years, in similar circumstances and with the same equipment, he lost eight more without winning a single set.

Is there a psychologist in the house please?

More recently Borg has played with great success on the Seniors Tour started by the irrepressible Jimmy Connors, whom he had beaten in the 1977 and 1978 Wimbledon finals.

In 2017, 2018 and 2019 he was the non-playing captain for Team Europe in the inaugural and second editions of the Laver Cup, guiding them to victory on all three occasions over Team World, coached by McEnroe.

"When I played tennis up to 25 everyone could only see the positive things about me, really," Borg told Adams. "Afterwards, if I did something negative, they always measured it against what I had done before. To be so perfect in my tennis, and as a person in some ways while I was playing, that was always going to be a hard act to follow."
